Abstract (en)
A receiver is provided capable of receiving both RDS (Radio Data System) and DARC (DAta Radio Channel) system FM multiplex broadcasting. An RDS signal demodulating circuit is provided with a PLL circuit which comprising a first frequency divider for dividing an output of a crystal oscillator, a phase comparator for inputting an output of the first frequency divider, a low-pass filter connected with the phase comparator, a VOC connected with the low-pass filter, and a second frequency divider for dividing an output of the VOC and outputting the divided output signal to the phase comparator. An output of the VCO is transmitted as a reference clock RDSCL for demodulation of an RDS signal. <IMAGE>
